摘要： A device for marking a work piece that is at least partially formed or reshaped through a thermal process is provided. The device includes a plurality of heating elements distributed laterally on a surface that is placed against the work piece and can be individually controlled for local heating of a work piece surface. Each of the heating elements includes a solid material with a surface structure and a heating structure. The surface structure includes at least one of a specifically or randomly varied topography. The surface structure can be at least partially heated through the heating structure.
